Well, heard about this "Caltrain Electrification Project" and wanted to build a scenario for it...there is a proposed service pattern in the net... but, couldn't find any "express pathes" (like there are for the already ingame Baby Bullet Services) in scenario planner to overtake the "all stopping services", even though for the Baby Bullet services right now in game, there are passes using the overtaking lines for example at Bayshore and Lawrence...
You can probably do what you want to in the Public Editor, rather than Scenario Editor, as you can use all sections of track in a route. Try scenario creation using that tool and learn how it works. Then when the editor is updated you will have creations ready to be released. I have no idea why DTG provide so few paths on their routes as it really limits gameplay. In many ways I think that the lack of paths is one of the biggest 'own goals' in the game.
